Hikaru Deguchi · CLIENT: D Code

D Code is a symbol mark based on traditional Japanese aesthetics and the idea of natural harmony. The composition follows the Silver Ratio of 1 to 1.414, known in Japan as the Yamato Ratio, a proportion long used in Japanese architecture and art. The form combines the five vowels of the Sacred Mizukuki Characters into a single shape. D Code is built in three layers: a white symbol, a mandala of 25 Mizukuki patterns, and a black symbol, reflecting the balance of yin and yang. The layered structure is reproduced with traditional Ukiyo-e printing techniques.

Unique Properties
D Code, The Ultimate Energy Symbol of Japanese Aesthetics
D Code is a symbol that embodies the spirit and natural beauty of Japan.
At its core lies the Silver Ratio (1:1.414), called the Yamato Ratio in Japan, a primordial proportion symbolizing the ideal form of natural harmony and beauty.

D Code is not merely a design.
It visualizes the unseen order of nature, the shimmering of a lake, the flow of the wind, the rhythm that resonates through all living things, manifesting as an energy device that enhances life.

Composed according to this sacred ratio, its three modes (The Beauty of Silence, The Beauty of Quiet Determination, and The Beauty of Coexistence) draw forth the inner power of those who behold or possess it, awakening harmony and resonance.

D Code is not decoration.
It is a Japanese symbol of beauty that aligns one's mind, body, and space with the universal laws of nature.

Production Technology
D Code is a three-layered symbol. The first layer is the white D-Code, the second layer is a mandala composed of 25 sacred Mizukuki Characters patterns, and the third layer is the black D Code. It incorporates the traditional Japanese concept of the harmony of yin and yang. This three-dimensional structure can only be reproduced using Japanese Ukiyo-e techniques. Although the second and third layers remain invisible, their presence amplifies the power of this symbol.
Inspiration
This symbol mark is inspired by Sacred Mizukuki Characters, said to appear on the surface of Lake Biwa in Japan on clear days. It combines the five great vowels of Sacred Mizukuki Characters, which are the source of all voices, into a single form. Sacred Mizukuki Characters are believed to be a script created by Great Nature (the primordial existence).
